Let me introduce you to "The Four Agreements" by Manuel Ruiz. This small yet powerful book has helped so many people including myself. Even the book will admit that the process of following these rules takes time and even to this day I wall pause and catch myself making an assumption and totally taking it to an uneccessary level. The taking thing personally part is rather difficult to say the least. The trick is everyone else is their own little universe. The things that they say or do are not always directly meant for us in any way shape or form. We've all felt personal attacks before but if you where to shine the light of truth over the matter, many of us would realize we where totally wrong from the start.
I suggest this book for anyone looking for a simple beginner step to a better overall outlook on this crazy life of ours.
